כְּפֶ֣רֶץ רָחָ֣ב יֶאֱתָ֑יוּ תַּ֥חַת שֹׁ֝אָ֗ה הִתְגַּלְגָּֽלוּ׃
Rashi on Job
As [through] a wide breach in a fence, through which everyone comes and passes through, so they come together against me to embarrass me.
Rashi on Job
under darkness they roll i.e., they come rolling along in secret until they reach me, to provoke me, so that I should not be able to escape from them.
